Item 4.Purpose of Transaction

The Reporting Persons purchased the Shares based on the Reporting Persons’ belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons believe that the Issuer remains undervalued and that additional value could be realized through pursuing a variety of strategic alternatives and pathways. To that end, the Reporting Persons have spoken with members of management from the Issuer for the purpose of proposing and helping to evaluate such strategic alternatives. The Reporting Persons intend to continue to engage in discussions with the Issuer’s management team and may engage in discussions with the Issuer’s Board of Directors, other stockholders of the Issuer and other interested parties regarding the Issuer’s capital allocation, corporate governance (including board structure and composition), operations, strategic plans and other means to enhance stockholder value.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and the Board of the Issuer, engaging in discussions with stockholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure (including board composition) or operations of the Issuer, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, or changing their intention with respect to any and all matters referred to above.

Item 5.Interest in Securities of the Issuer.

(a)The following percentages are based on a denominator which is the sum of: (i) 21,816,041 Shares outstanding, which is the total number of Shares outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on October 29, 2018 and (ii) the 992,750 Shares underlying certain Warrants, as applicable.

As of the close of business on January 31, 2019, the Reporting Persons hold 7,234,285 Warrants exercisable for an aggregate of 7,234,285 Shares. Such Warrants have an initial exercise price of $0.01 per Share, subject to adjustment pursuant to the terms of the Warrants. The Warrants are only exercisable to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would not beneficially own more than 9.99% of the outstanding Shares after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the Warrants (the “Beneficial Ownership Limitation”). As of January 31, 2019, the Beneficial Ownership Limitation limits the aggregate exercise of the Warrants by the Reporting Persons to 992,750 out of the 7,234,285 Shares underlying the Warrants owned by the Reporting Persons in the aggregate. In providing beneficial ownership described herein, the Reporting Persons have assumed 992,750 of the 3,590,789 Warrants owned by BVF would be exercised. BVF2 holds Warrants to purchase 2,296,089 additional Shares which are excluded herein as a result of the Beneficial Ownership Limitation. BVTOS holds Warrants to purchase 615,779 additional Shares which are excluded herein as a result of the Beneficial Ownership Limitation. The Partners Managed Accounts holds Warrants to purchase 731,628 additional Shares which are excluded herein as a result of the Beneficial Ownership Limitation.

As of the close of business on January 31, 2019, (i) BVF beneficially owned 1,336,100 Shares, including 992,750 Shares underlying the Warrants that are currently exercisable, representing percentage ownership of approximately 5.9% of the Shares outstanding, (ii) BVF2 beneficially owned 795,623 Shares, representing percentage ownership of approximately 3.7% of the Shares outstanding, (iii) Trading Fund OS beneficially owned 106,239 Shares, representing percentage ownership of less than 1% of the Shares outstanding and (iv) 40,636 Shares were held in the Partners Managed Accounts, representing percentage ownership of less than 1% of the Shares outstanding.

Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own the 106,239 Shares beneficially owned by Trading Fund OS, representing percentage ownership of less than 1% of the Shares outstanding.

Partners, as the general partner of BVF and BVF2, the sole member of Partners OS, and the investment manager of Trading Fund OS and the Partners Managed Accounts, may be deemed to beneficially own the 2,278,598 Shares beneficially owned in the aggregate by BVF, BVF2, Trading Fund OS, and the Partners Managed Accounts, representing percentage ownership of approximately 9.99% of the Shares outstanding.

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 2,278,598 Shares beneficially owned by Partners, representing percentage ownership of approximately 9.99% of the Shares outstanding.

11

Mr. Lampert, as a director and officer of BVF Inc. may be deemed to beneficially own the 2,278,598 Shares beneficially owned by BVF Inc., representing percentage ownership of approximately 9.99% of the Shares outstanding.

(b)Each of BVF, BVF2, and Trading Fund OS, shares with Partners voting and dispositive power over the Shares each such entity beneficially owns. Trading Fund OS, shares with Partners OS, voting and dispositive power over the Shares beneficially owned by Trading Fund OS. Partners, BVF Inc. and Mr. Lampert share voting and dispositive power over the 2,278,598 Shares they may be deemed to beneficially own with BVF, BVF2, Trading Fund OS, Partners OS and the Partners Managed Accounts.

(c)No Reporting Person has entered into any transactions in the Shares during the past sixty days.

(d)No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Shares.

(e)Not applicable.

Item 6.Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

On February 1, 2019, the Reporting Persons entered into a Joint Filing Agreement in which the Reporting Persons agreed to the joint filing on behalf of each of them of statements on Schedule 13D, with respect to securities of the Issuer, to the extent required by applicable law. A copy of this agreement is attached hereto as Exhibit 99.1 hereto and is incorporated herein by reference.

Partners is the general partner of each of BVF and BVF2 pursuant to limited partnership agreements which authorize Partners, among other things, to invest the funds of BVF and BVF2 in the Shares and other securities and to vote, exercise or convert and dispose of such securities. Pursuant to such limited partnership agreements, Partners is entitled to receive fees based on assets under management and allocations based on realized and unrealized gains on such assets.
